Doofus, bless his heart, is not the sharpest anything in the anywhere. His deafness has been accounted for, his imperfect sight has been accounted for, but to all intents and purposes the poor thing is Definitely A Bit Thick. It's probably a result of the rampant inbreeding that resulted in him, perpetrated by an irresponsible breeder who was ejected from Sosin tribe not long afterwards. Doofus drools rather a lot and has no idea where he's putting his feet, but he has a cheery heart of gold even if he has a brain of glitter.
